Apple has officially seeded the first public beta for iOS 9.3.3. Yesterday Apple seeded the first developer beta, which appears to be focused on behind-the-scenes fixes and tweaks for iOS devices. The first beta releases for iOS 9.3.3 arrive just one week after the public release of iOS 9.2.3.
The beta update is available as an over-the-air (OTA) software release for devices registered with Apple’s beta program. If you haven’t yet, and want to, you can do so through Apple’s beta testing website.
